MetaMemento: Enriching Physical Objects with Digital Layers

We present MetaMemento, a mixed reality (MR) tool designed to enhance the personal significance of physical objects by overlaying digital content. This tool allows users to author personal meta-data, such as images, music, and notes, to their physical belongings, creating unique MR mementos. By leveraging the concept of non-fungibility, MetaMemento combines physical and digital ownership. This paper details the development and user experience design of MetaMemento, highlighting its potential to blend digital and physical realities and foster deeper connections with personal items.
